A method for increasing a quality of sampled receive signals includes: generating a plurality of sampling signal repetition rates with a running variable; determining a receive signal repetition rate associated with each of the sampling signal repetition rates; generating a receive signal sequence consisting of the receive signals; generating a sampling signal sequence consisting of the sampling signals; generating a mixed signal sequence; low-pass filtering the mixed signal sequence; determining a quality indicator of the low-pass filtered mixed signal sequence; selecting a quality indicator which exceeds a predetermined quality threshold from the determined quality indicators; and using the sampling signal repetition rate and the receive signal repetition rate associated therewith. A related measuring device is also disclosed.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method according to claim 1, wherein a start sampling signal repetition rate fA,W,0 and an interpolation factor N∈{≥3} are predetermined, wherein a new set I={i:i∈{1, . . . , N}⊆I and (i+N)∈} is determined, and wherein then the sampling signal repetition rates according to fA,W,i=fA,W,0(1+(i−1)/N) are determined only for i for all i∈I.
3. The method according to claim 1, wherein a start sampling signal repetition rate fA,W,0 and an interpolation factor N∈{≥3 and N∈} are predetermined, wherein a new set I={i:i∈{1, . . . , N}⊆I} is determined and then the sampling signal repetition rates according to fA,W,i=fA,W,0 (1+(i−1)/N) are determined only for i for all i∈I.
4. The method according to claim 1, wherein each of the receive signals is a pulse and/or each of the sampling signals is/are Dirac pulses.
5. The method according to claim 1, wherein each of the quality indicators is a signal-to-noise ratio of the low-pass filtered mixed signal sequence.
9. The measuring device according to claim 7, wherein the measuring device is a level measuring device and the measuring probe is a level measuring probe.
